Do i pay sales tax if live in Oregon buy used car ca?

No, you do not have to pay sales tax if you live in Oregon and buy a used car from California. This is because Oregon does not have a sales tax, while California does. When you purchase a used car from another state, you are not required to pay sales tax in the state where you purchased the car. Instead, you will pay sales tax in the state where you register the car. Since you live in Oregon, you will pay Oregon sales tax when you register the used car.
